Title: Method of signalling
Inventor: COWDERY CHRISTOPHER JAMES
IPC: H04L1/24
Filed: 2004-03-31
Granted: 2007-09-12
Abstract: Signalling between a first and second device (2,3) linked by a transmission line (8) and of sensing a security violation of the line (8) comprises the steps of (a) transmitting a signal from the first device to the second device, reflecting the signal back to the first device in a manner corresponding to a first bit sequence, receiving the signal thus reflected at the first device, and comparing this signal with the transmitted signal to determine whether there has been a security violation of the line and to extract the first bit sequence. This can be detected by measuring the round trip time of a reflected signal. A variation in trip times indicates a change in impedance which may be caused by a third party attempting to 'tap into' the communication line.

Granted: 1993-03-24
Abstract: A gas injection or aeration device, adapted to be immersed in a liquid and supplied with gas under pressure so that the gas emerges through diffusion nozzles of the device as a large quantity of small bubbles to form a liquid-gas mixture. The device includes a substantially vertically disposed riser tube which can be an open-ended conduit or can be defined, in use of the device, by a curtain of the rising bubbles. A sleeve, in which the nozzles are formed as apertures, expands under pressure of the gas supplied to admit the gas into the liquid and then contracts to partially or wholly close the nozzles when the gas supply is subsequently turned off. The nozzle aperture may comprise an elongate slit of generally corrugative form. An undertube may extend, in use of the device, below the nozzles to entrain liquid to rise towards the nozzles.

Title: Offset calibration of a DAC using a calibrated ADC
Inventor: SOOCH NAVDEEP SINGH
IPC: H03H17/02
Filed: 1992-08-21
Granted: 1995-11-08
Abstract: A calibrated digital-to-analog converter (DAC) is provided that includes a DAC having an interpolation circuit (40) and delta-sigma converter (44). The output of the delta-sigma converter (44) is input to a one-bit DAC (48) and the output thereof filtered by an analog low pass filter section (50). During a calibration procedure, a calibrated analog-to-digital converter (ADC) (22) is utilized that is operable to receive the analog output of the DAC with a "0" value input thereto through a multiplexer (58). The output of the ADC (22) represents the inherent error in the delta-sigma converter (44) and the analog filter section (50). This is stored in a register (62). In a second step of the operation, the contents of the register (62) are input through the interpolation circuit for interpolation thereof and storage in an offset register/latch circuit (56). The contents of the latch (56) are input to a summing junction (54) which, in normal operation, are summed with the output of the interpolation circuit (40) for input to the delta-sigma converter (44). By disposing the summing junction (54) between the interpolation circuit (40) and the delta-sigma modulator (44), the bit load on the input of the interpolation (40) can be reduced. By utilizing the interpolation circuit (40) in the calibration procedure, the gain thereof can be compensated for in the value stored in the register/latch (56).

Title: Substrate regenerating biosensor
Inventor: HILL NORMAN
IPC: C12Q1/00
Filed: 1992-10-16
Granted: 1993-09-15
Abstract: A biosensor for the detection and determination of the concentration of toxins by use of enzyme inhibition. Inhibition biosensors are affected by non-specific denaturation and substrate utilization which both result in a limited operational lifetime. These problems are mitigated by providing in an environment an enzyme which is oxidized by hydrogen peroxide the oxidized enzyme being reduced by an electron transfer agent, such as ferrocene, which is itself oxidized in the process. The electron transfer agent is capable of regeneration back to the reduced state and the extend of electron transfer regeneration gives a measure of enzyme inhibition by toxin. Electro-chemical technique allows for the generation of hydrogen peroxide from oxygen in aqueous media and the reduction of oxidized electron transfer agent. Immobilization of the enzyme to an electrode increases efficiency while potentially reducing denaturation. The biosensor can be used for the environmental determination of toxins like cyanide.

Title: Fastener applicator
Inventor: BURLINGTON GEOFFREY MICHAEL
IPC: F16F15/30
Filed: 1992-12-10
Granted: 1995-02-22
Abstract: A fastener applicator, for example for cable clips, uses the kinetic energy of a flywheel (6) rotated by a prime mover (4), preferably a battery drive electric motor, to drive a striker (8) for firing a fastener into a support. An actuator (7) which strikes the striker (8) may be a fixed projection on the flywheel (6) or be an element on the flywheel movable relative to the flywheel by centrifugal force to project the actuator from an inoperative position to an operative position for striking the striker. The driven from the prime mover (4) to the flywheel (6) is through a clutch or releasable drive coupling (26) which temporarily disconnects the drive when the actuator strikes the strike so that the kinetic energy at the flywheel alone drives the striker and the prime mover is protected from the impact. In a modification a micro-processor measures the rotational speed of the flywheel and stops the prime mover when a pre-determined speed for the necessary kinetic energy is achieved. <IMAGE>

Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.
